1 Claim.

This invention relates to improvements in cleaning devices. More specically, it relates to brushes for cleaning screens, windows, etc.

I am well aware that there are other brushes adapted to receive and dispense liquids, but these are not practical for the purpose aforementioned. With my device, all that is necessary is to grasp the brush with one hand, and the other hand is left entirely free to grasp screens, etc., turn them for cleaning on both sides and on both ends.

With the device of my invention, it is possible to turn the brush at will to any angle, and get into the places where the dirt collects most, into corners, both horizontal and vertical, also rightangled and other corners.

The facility of handling of the brush of my invention will be best understood by those who have had to do this kind of work, including janitors.

Another object, among others, of my invention is an improved construction for providing a brush of the fountain type. According to 'the principle of my invention, I provide a pair of brushes or brush sections with the usual bristles, as indicated in the drawing. Between the brush heads, I have provided a water supply comprising a tubular piece of metal which is apertured, as are the brush heads to receive a bolt, by means of which, together with a nut, the parts are adapted to be locked together, as will be more fully apparent from what appears hereinafter.

The tube is provided with outlets for supplying the bristles with Water, liquid soap, or other fluid.

The tube is adapted to extend beyond the ends of the brush heads, to form a handle, by means of which the device may be grasped, to both brush and wash a screen or window or other device.

The tube will also be provided with a coupling for a hose, or the like.

These and other objects and advantages will appear and be brought out more fully in the following speciiication, reference being had to the accompanying drawings, in which:

Fig. l is an elevation view of the device.

Fig. `2 is a section on the line 2-2 of Fig. l.

Referring to the drawings in detail, in which I have shown the preferred form for the purpose of illustrating the principle of my invention, I have shown a pair of brush sections 5 and 6, having bristles l.

The brush heads or sections are apertured as at 8 to receive a bolt 9, having a head I0 and a lock nut I I.

Adapted to be positioned between the brush sections, is a tube I2 made of brass or other suitable metal or plastic, as desired.

The tube is also apertured as at I3 to receive the bolt 9, to secure the tube to the brush heads.

The tube is provided with apertures I4, there being as many as is desired, with the apertures being located approximately in the center of the lower half of the tube.

The tube is adapted to have a sleeve I5 of rubber or the like for convenient and comfortable handling. The tube is also adapted to be provided with a coupling I6 to a hose or the like.

The manner of operation will be apparent. The user, who is cleaning screens 0r windows, or other appropriate articles may hold the screen in one hand and apply the brush and the water, or other liquid, With the other hand in a most eflicient manner, in addition to saving of time and steps and other effort.

While I have illustrated and described the preferred form of construction for carrying my invention into eiect, this is capable of variation and modication without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variation and modifications as come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A brush assemblage for cleaning screens, Windows, and the like, comprising: a pair of elongated brushes, each having a base portion, said base portions being disposed side by side in spaced relation, and each having elongated tufts of exible bristles extending laterally therefrom and lying substantially in parallel planes; the free ends of all of said bristles lying in a common plane, a pipe extending longitudinally of the base portions of said brushes, and between the same, said pipe being closed at one end and terminating adjacent one set of ends of said base portions, and having a portion projecting longitudinally beyond the opposite set of ends of said base portions to form a handle, said projecting portion adjacent to its outer extremity having an inlet for the entrance of liquid, and said pipe between said base portions having openings ior directing liquid between said bristles; and means extending through said base portions and said pipe for simultaneously securing the same in assembled relation.
